Once the colour segmentation is completed, and the labelled image displayed in the Imcalc Tv, the regions covered by each label
can be selected by entering the label in the "Label" field, and pressing "select". This will generate a binary image where the
pixels having the desired label are white, and all other pixels are black, and place this image second on the stack for display
in the Imcalc2 Tv. The number of pixels selected will also be displayed in the text window of the top-level tinaTool. The
original labelled image will not be disturbed, allowing repeated application of this button for study of the segmentation result.

The binary images can also be used as multiplication masks. Use the store function in Imcalc to store a copy of the mask, and
push each of the red, green and blue fields to the stack. Multiply each field by the mask in Imcalc, and pop it back into the
Colour Tool. The masked colour image can then be output as a ppm image, providing a colourful way to display the segmentation
result.
